SPECIFICATION forming part of Letters Patent No. 228,103, dated May 25, 1880.

Application filed March 18,1880. (No model.)

To all whom it may concern Be it known that I, PHILIP A. MYERs, of Ashland, in the county of A shland and State of Ohio, have invented a new and useful Improvement in Force-Pumps, of which the following is a specification.

My invention consists in a novel construction, arrangement, and combination of the various parts of a pump, whereby simplicity, economy, and efficiency are obtained, as hereinafter particularly described.

In the accompanying drawings, Figure 1 represents a central vertical longitudinal section of a pump embodying my improvements. Fig. 2 is an exterior view at right angles to Fig. 1.

Similar letters of reference indicate corrc sponding parts. 7

A represents the pump-cylinder, which is formed with a lateral extension, B, communicating therewith by a port or passage, 0. These parts are made of metal and in one piece.

D represeii ts the suction-pipe, which is made of wood, and is inserted in the lower end of the cylinder A, and is secured thereto by means of a staple, E, surrounding the pipe D, and passing through lugs a a on a plate formed with the cylinder, and fastened by nuts e.

G represents the discharge-pipe, which is made of wood, and is inserted in the upper end of the extension B, and is secured in place bYjJlGEbHS of a staple, H, surrounding it and passing through lugs ff, formed on the upper part of the cylinder, and fastened by nuts h.

J represents the air-chamber, provided with a spout, t. The air-chamber is made of metal,

and rests on the upper end of the dischargepipe G, which is inserted therein.

K is the pump-lever, which has its fulcrum on a standard, 1, formed on the top of the airchamber J. M is the pump=rod, carrying two pistons, m m which work in the cylinder A.

P is a metal pipe, having its upper end flanged, and resting in a seat, j, in the bottom of the air-chamber J, just over the upper end of the discharge-pipe G. The lower end of the pipe P has attached to it a screw-bolt, R, which passes through the bottom of the eX- tension B, and is fastened by a nut, r. In the pipe P is a port or passage, .9, opposite to and communicating with the port or passage 0.

The various parts being secured together, as shown and described, the wooden dischargepipe G serves also as the pump-stock, and the metal pipe 1? serves also as a rod or bolt for holding the cylinder and extension, the discharge-pipe, and the air-chamber firmly and securely together.

When the pump isin use the water basses from the suction-pipe D into the cylinder A, and from thence through the ports 0 and ,9 up the pipe P to the airchamber J.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent The combination of the cylinder A, extension B, pipe P, and ports 0 and s with the pipe G and air-chamber J, as shown and described, for the purpose specified.

PHILIP A. MYERS.
